Owning a car means dealing with ongoing maintenance, and a worn set of tires makes every commute feel rough. November is usually the softest time of year for tire prices, right when major brands launch seasonal markdowns and stackable rebates.
Buying four quality tires at once hurts less when you separate the sticker price from your monthly cash flow. If you use a zero-interest window strategically, you can upgrade your ride without draining your checking account.
A 0% interest period is a strict deadline, not free money. If you still have a balance when the 18 months end, the regular interest rate kicks in on whatever is left, making those tires far more expensive.
